While it has had MANY moments, it has been very financially beneficial.

Currency conversion dynamics can be a huge factor in foreign investment, one I had largely overlooked.Yes, that exchange rate does takes a big bite, but that's possibly where owner financing could be beneficial.

@Cameron PriceI agree with comments above that if you qualify for the Solo 401k plan I don't see any reason why SD IRA would be more beneficial (unless you have funds in a Roth IRA like Chris).

I would respectfully disagree and I believe the two are mutually exclusive...and should be.  

I was introduced to BP podcasts about a month ago and have found them to be extremely beneficial.  

I believe that it would be beneficial.

A properly structured contract would allow you to take over conttrol of the project without foreclosure by shifting the beneficial interest from the investor to you as project milestones are missed.I realize this suggestion comes a little late in the game for your current situation, so give CRR a call, but before the next time look into using a land contract.

We have a signed, executed lease agreement and did not mutually agree to terminate lease.

It just burns me up to have money sitting in mutual funds going nowhere right now and I'm feeling pressure in my 40's to get my financial situation in a better place.Anyone have any words of encouragement or caution?

Perhaps we can connect to see if there are any areas of mutual benefit.
